First hydro Grow -Update Day 57
Hello together!
First grow is going pretty fine, I am still facing some problems though…
The first two plants (picture 1 and 2) are going good (both Gorilla Cookies Auto by fastbuds) they are in week 4 and 3 of flower and they seem to end with some really nice buds!
The plant in the back though (other pictures, this is a Gelato Auto by fastbuds) is in week 2 of flower and kind of stopped growing that fast.
It keeps dropping the leaves and the leaves curl inwards a bit lengthwise. This happens after around 14 hours of light. The tips of the leaves are a little bit yellow, so I maybe think of light stress? The ppfd is around 650-850.
Temperatures at day are around 22-26 degrees C° and at night they drop to around 12-15 degrees. I already changed the light hours from 07 am- 01 am to 6 pm-12pm so they don’t get so cold anymore.
I still run my hydro system with h2o2 and didn’t really notice any root rot or damage. They do look a bit brown at some spots, but are mostly white also at the tips. The pots are around 15 liter but the gelato has grown so big, the roots fill out 8/10 of the water part in the pot. I will send more pictures when I get my new phone, old one broke and the pictures are taken with my iPad.
I also had delivery problems with my fertilizer (terra aquatica tripart bloom) so I needed to cut nutrients and added a different bloom fertilizer with different specs.
EC is around 1,6 and I keep the ph between 6,0 and 6,4 with some spikes up to 8,0 sometimes when the water level drops too fast without me noticing…
I took one plant out of the SCROG and pot and there are some build ups at the bottom (easily removable by swiping with my hand). But since I can’t remove the plants out of the pots to clean (because they grown into the nets) I only flushed the entire system with 150 liter clean water, before filling it up almost new (old last 20% of system water was diluted multiple times), with fresh water and nutrients.
I still think at least 50% of bottom build up is there though…
Can anyone help me identify the problem and solve it?? 💚
